Subject: [PATCH] feat(languages): add Go, Java, PHP, Ruby, C/C++ tree-sitter
 support (closes #198)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Add 6 new language entries to node_types.yaml:
- Go: function_declaration, method_declaration, struct_type, interface_type,
  import_declaration, call_expression, etc.
- Java: method_declaration, constructor_declaration, class_declaration,
  interface_declaration, enum_declaration, method_invocation, etc.
- PHP: function_definition, method_declaration, class_declaration,
  include_expression, use_declaration, function_call_expression, etc.
- Ruby: method, singleton_method, class, module, require, call, etc.
- C: function_definition, struct_specifier, union_specifier, enum_specifier,
  preproc_include, call_expression, type_definition, etc.
- C++: function_definition, class_specifier, struct_specifier, preproc_include,
  using_declaration, call_expression, namespace_definition, template_declaration,
  type_alias_declaration, etc.

Each language has minimum 4 required categories: function_def, class_def,
import, call. Additional categories added where the language has unique
constructs (e.g. Java annotations, PHP namespaces, C++ templates).

Grammar packages added to pyproject.toml [project.optional-dependencies]
grammars: tree-sitter-go, tree-sitter-java, tree-sitter-php,
tree-sitter-ruby, tree-sitter-c, tree-sitter-cpp.

Verified: codelens scan on test fixture with all 6 languages — 6 files
detected (go:1, java:1, php:1, ruby:1, c_cpp:2), 12 backend nodes, 0
crashes. get_supported_languages() returns 13 languages (7 existing + 6
new).

Definition of Done (issue #198):
- [x] node_types.yaml has entries for Go, Java, PHP, Ruby, C, C++
- [x] Each entry has minimal 4 categories: function, class, import, call
- [x] Grammar packages added to pyproject.toml
- [x] codelens scan does not crash on new languages
- [x] Files in new languages are detected and scanned (not skipped)
